TYPE-WRITER CABINET.

SPECIFICATION forming part of Letters Patent No.

719,419, dated February 3, 1903.

Application filed September 8, 1902. Serial No. 122,502. (No model.)

To a/Z whom t may concern.-

Be it known thatI,GLENN J. BARRETT, a citizen of the United States, residing at Grand Rapids, in the county of Kent and State of Michigan, have invented certain new and useful Improvements in Type-Vriter Cabinets; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in type-writer cabinets; and its object is to provide a device in which the movable parts are supported upon rigid arms or brackets pivoted to the sides of the case, whereby they serve to brace and strengthen the case; to provide a device that is not readily got out of order by warping and shrinkage of the movable portions; to provide a device in which the movements are such as to avoid collision of the type-writer with the movable portion of the top; to provide means whereby the movable parts are held securely in place when the device is either open or closed;

Ato simplify the construction, and to provide the device with certain new and useful features hereinafter more fully described, and particularly pointed out in the claims.

My invention consists, essentially, in the movable portion of the top and the shelf that supports the type-writer, rigid arms attached to the same and pivoted to the case, a camsurface on one of the arms supporting the shelf, and an extension on one of the arms supporting the movable portion of the top and slidably engaging the cam-surface, as hereinafter more fully described, reference being had to the accompanying drawings, in which- Figure l is a vertical section, on the line l l of Fig. 2, of a device embodying my invention and showing the cabinet closed. Fig. 2 is a front elevation of the same, showing the cabinet open.

Like letters refer to like parts in both of the figures.

A represents the case proper, consisting of any suitable structure in two principal parts,

and having a middle space between, commonly known as the well, said parts being connected in any suitable manner at the rear and top, and open at the front.

B is the fixed portion of the top, extending across the rear portion of the well and at each side thereof.

C is a movable portion of the top, which when the cabinet is closed is supported in the plane of the top B and above the well and completes the top. This portion C is supported upon arms F, rigidly attached to the respective ends of the same and extending downward therefrom and pivoted upon plates J, secured to the side walls of the Well and adapted to turn backward on said pivots and carry the movable portion C of the top backward and downward within the well to a substantially vertical position, as shown in Fig. 2 and in broken lines in Fig. l.

D is the shelf to support the type-writing machine, which shelf is supported at each side upon the arms E, rigidly attached thereto and extending downward and pivoted at their lower ends to suitable plates I, attached to the sides of the well. These arms are adapted to turn from vertical to inclined position and carry the shelf D inward within the well to an inclined position, as shown in Fig. 1, and to return to a vertical position and support the said shelf in a horizontal p0- sition, with its upper and outer edge projecting outside the case, as indicated by broken lines in Fig. l, thus dispensing with any occasion for a sliding support for the typewriter. A cam E is also provided on the under side of the shelf, preferably formed integrally with one of the arms E and adapted to slidably engage the end of an extension F of one of the arms F, which extension is curved rearward and downward and thence upward and extends through a suitable recess in the edge of the shelf D and is preferably provided with a friction-roll G.

The surface of the cam E, which engages the roll G, is so formed as to be nearly concentric with the axis of the pivot of the arm F, whereby in opening the device the shelf D moves but very little until the top portion C is moved back to a considerable extent and is well out of the way of the path of the typewriting machine as the same rises. The roll G having traversed the cam E then commences to lift the shelf to place, and when the shelf has reached a horizontal position stop-blocks H engage the shelf and prevent its further movement. The top C now serves as a weight and the arms attached thereto as levers, and thus effectually supports the shelf in place by the engagement of the roll G with the under surface of the cam E.

In closing the device reverse movements occur, the shelf D being lowered to the closed position early in the movement of the top C upward and forward. The weight of the shelf and type-writer now rests on the extension of the arm F and serves to securely hold the device in closed position. It will also be observed that the top C and the shelf D are e'ach supported upon a pair of rigid arms'pivoted to the sides of the case by means of the plates I and J, whereby any shrinkage or warping of the top C and shelf D will have but little, if any, effect upon the operation of the device. It will also be observed that the device consists of but very few parts, easily and cheaply constructed, and not likely to get out of order.

I have shown but one side only provided with the cam E and extension F. It is obvious that both sides may be provided with the same, if desirable.

Having thus fully described my invention, what I claim, and desire to secure by Letters latent, is-

l. In a type-writer-cabinet, the combination of a case, a movable top, a movable shelf, arms rigidly attached to each and pivoted to the case, and a rigid extension on one of the arms of the top and slidably connected to the shelf.

2. In a type-writer cabinet, the combination of a case, a movable shelf, arms rigidly attached to the shelf and pivoted to the case, a cam on the shelf, a movable top, arms rigidly connected to the top and pivoted to the case, an extension on one of said arms, and movably engaging the cam on the shelf.

3. In a type-writer cabinet, the combination of a case, a top and a shelf pivotally supported in the case, a cam on the shelf and substantially concentric with the pivot of the top when the cabinet is closed, and an arm rigidly attached to the top, and engaging the cam, and intermedially pivoted to the case.

4. In a type-writer cabinet, the combination of a case, a movable shelf, arms rigidly attached to the shelf and pivoted to the case, a cam on one of said arms, a movable top, and arms rigidly attached to the same and pivoted to the case and also having a curved extension movably engaging the cam to move and support the shelf. p

In a type-writer cabinet, the combination of a case, a movable shelf, arms rigidly attached to the shelf and pivoted to the case, a cam on the shelf, a stop to engage the shelf when horizontal, a movable top, an arm rigidlyattached to the same and pivoted to the case, a downward and forward extension of said arm, and a friction-roll on the end of the same, and engaging the cam on the shelf.

In testimony whereof I affix my signature in presence of two witnesses.

GLENN J. BARRETT.
